: pelling means, propelled by wind or-othencated any manner in g I sociatedwith the headlight2 of conventional i r or other.' form,: which gheadligh t'has thensualj i lightjsoinrce 6, and the reflectors, It will;

practice the shaft 22 and bearings 18 may be lubricated in any suitable manner.

Preferably mounted externally of the member 10 is a propelling means comprising any preferred number of blades, preferably two in number and shaped as shown, and positioned in offset and in inclined relation to each other as more particularly shown in Fig. 2, to provide for an eiiicient rotation thereof, by the wind, as the motor vehicle moves forwardly, said blades being suitably connectedto a hub by means of which said propelling means may be detachably mounted upon the rotatable shaft 22 in any preferred manner. The propelling means 44- itself functions a glare eliminator, the rays of light coming from the light source 6 and reflected by the reflector 4, being sheared by the blades of said means, materially assisting in removing the objectionable glare from the headlight or other illuminating means.

On the other side, and internally of the transparent member 16, is positioned the combined light collector and glare eliminating means, designated generally by the reference numeral 32, said means comprisinga light collector ring 34, which has a mounting 4O extending'thereacross, which mounting-is centrally provided with a hub 42- by which, said light collector ring is mounted upon the shaft 22, as by screwing the same thereon, the propelling means 44 being adapted to rotate said light collector ring by means of said shaft.

If desired, the periphery of the light collector ring 34 may be provided with suitable cut-out or cut away portions (Figs. 1 and 2) to assist in shearing the light rays coming from the light source 6to assist in eliminating the objectionable and dangerous glare.

Another very important feature of my invention resides in the adjustable glare eliminating rings 38 (Figs. 3 and 4, more particularly) which rings may be fiat, and are providedwith a suitable adjusting means, such as the screw bolt, and nut assembly 36, operable in the slots 35 (Fig. 3.) in the member 40. This construction permits the rings 38 to be adjusted toward and away from each other, so they will overlap, a portion of one of said rings being positioned in substantial alignment with the light source 6, thus effectively insuring that the light rays will be sheared when the glare eliminator 32 is rotated by the propelling means 44.

Should it be desired to accentuate the light from the light source 6, such as on a foggy night, the rings 38 are adjusted so they will be placed in alignment, thus concentrating the light rays in one light beam, which has a marked light penetrating effect.

In accordance with the provisions of the patent statutes, I have described the principle of operation of my invention together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means.

I claim as my invention:

1. In a glare eliminator for use in connection with the reflected light of a light source, a transparent member through which the rays of said light source are adapted to pass, means on the inside of said transparent member for shearing said light rays, and means on the outside of said member for propelling said last mentioned means.

2. A glare eliminator adapted for use in connect-ion with a light source, a transparent member through which the rays of'li-ght from said light source are adapted to pass, revoluble light shearing means on one side of said member, and means on the other side of said member for rotating said light shearing means.

3. A glare eliminator adapted for use in connection with a light source, a transparent member associated with said light source, revoluble light shearing means on one side of said member, means associated with said light shearing means for adjusting the latter with respect to the candle power ofsaid light source, and means for propelling said light shearing means on the other side of'said member.

4'. A glare eliminator adapted for use in connection with a light source, a transparent member associated with saidl'ightsource, adjust-able light shearing means on one side of said member, and wmdpropelled' means on the other side of said member for propelling said light shearing means, pelled meansbeing also a means.

5. A glare eliminator adapted for use in connection with a light source, a transparent member associated with said light source and said wind prol'ight shearing combined light shearing and light collecting means on both sides of said member whereb the glare of said light will be eliminated but at the same time accentuate said light source.

6. In a glare eliminator adapted for use in connection with a light source and a light reflector, a transparent member, a combined light shearing and propelling means on one side of said member, and a combined light collecting and light shearing means on the other side of said member, said propelling means being adapted to propel said combined light collecting and light shearing means.

7. A combined light collector and light shearing means adapted for special use in connection witha light source and its reflector, a light collector ring, having means for shear ing the rays of light from said light source,

and at least two adjustable light shearing rings associated with said ring for shearing,

the light from.

said rays of lightyaccording' to the candle v 7 power thereof, a portion of one of said rings being in direct alignment with. said. light 7 source when the glare thereof is tobe'elimi- ,nated, said rings being positioned in a1ignment when said light is tobe accentuated.

8. Glare eliminating means adapted for special use in connection with a light source and its reflector, a transparent vmember, a

shaft extendingcentrally through said member, anti-friction means associated with said shaft, said shaft being adapted to be lubri cated, and glare eliminating means detachably mounted on said shaft on both sides of said member, one of said means being adapted to propel the other. I V

In testimony whereof I have signed my name to. this specification.
